MH/HH-60G
I don't know much about the Italeri MH-60G kit, just the Minicraft kit. Yes, the Minicraft windsheild is one-piece. Do you have a specific Pave Hawk you're wanting to build? Try to get as much as you can about a specific bird and go from there. SOF machines change
a lot so what was accurate two years ago, may not be the case right now. Salbando and I are working on a site to help out modelers of the Pave Hawk so either of us will have pix we can share in the meantime.
Out of the box, the Minicraft kit is a decent representation of an MH-60G from 1990/1991. The instructions call for installing the .50 cals in the main doors. Don't. They tried this out and it interferes with movement in and out of the birds too much. Even in a two-ship situation where one Pave Hawk is doing the pick up and the second one, armed with the extra guns is flying cover; what happens if something happens to the pick-up ship? The back-up becomes the primary and he's got a couple of guns getting in the way of things. So they don't use the .50 cals
For a late model HH-60G Pave Hawk, raid parts from CC 48031 - MH-60L Conversion set. I know, that sounds a little weird but it works. The parts you'll need are the chaff and flare dispensors, ALQ-144 IRCM, front and rear rocket plume detectors, laser detectors, misc. external antennas, vac windows (no framework), the well detailed seats and two nicely detailed miniguns with mounts, ammo cans and flex chutes. You might could even get away with using the CC cockpit and center console. They're better detailed than the original kit parts. There are radio and countermeasure racks aft for the pilot and co-pilot that will need to be scratchbuilt. Don't throw out the .50 cals as some late model HH-60Gs have used these in the gunner's windows instead of the miniguns. Again, check your references.

MH-60L
MH-60L and MH-60K are two very different machines. Quick backstory, the 160th SOAR started with MH-60As (UH-60As with a FLIR turrent and NVG cockpit), then they modified UH-60Ls as a temporary solution until the purpose-built MH-60K came into service. It was intended that once the Kilos arrived, the Limas would be transferred to Reserve units. Well, the Lima is still a good machine and still with the 160th. They've been upgraded over the years and rumor has it they're getting an engine upgrade in the near future that'll improve their performance over the Kilo.
Limas can also be used as DAPs (Direct Action Penatrator) and are sometimes called AH-60Ls when in this configuration. Basically what this is, they atttach shortened ESSS wings (one pylon per wing instead of the normal two) and hang rocket pods, Hellfire and/or the M230 chain gun (the one used on the Apache and the subject of CC set 48034). The miniguns are pointed forward and controlled by the pilot or co-pilot instead of the gunners. When in this configuration, they're not carrying troops.
Revell actually makes a MH-60L in 1/48 scale. I haven't built it, but I do want a Lima in that scale. If you can't get your hands on one of those, then a Minicraft UH-60L or MH-60K kit with CC set 48031 will work. You'll need to get 48034 if you want to finish it as a DAP.
MH-60K
Minicraft makes a MH-60K kit, but it's got a lot of accuracy problems, especially around the nose. That's where CC 48002 comes into play. It's the same kit as their UH-60L, but with a lot of extra parts.

This thread started off about rotor tips, then got seriously sidetracked before coming back around to rotor tips. Good news is, the sidetrack was Nightstalker color schemes.
