I have cut my aftermarket usage back a bit. I now only use what is really necessary, or things that really make my life easier. A few examples can point this out. I don't scratchbuild RF noses for a Cougar, I use one of the two conversion kits for that. AD-5W radomes are another spot, it is just so much easier to cut out and clean up, and then glue on the Falcon vac radome, than to follow the old Airfix instructions that I used to make a balsa wood radome for my AD-4W. (built a very long time ago)
I don't cut, carve, sand, etc, the parts to make a Mk 7 for a Nuke A-1, I just use one of the resin Mk 7 I bought from Spectre. I use aftermarket weapons whenever I can get them, it saves so much time over making a master to cast my own. Things like a 1/72 scale Gatling for the AC-47,,,,,,nope, not going to scratch build 4 of those, I just buy the Quickboost set.
I don't use Aftermarket in the cockpits anymore, either,,,,,,,just a resin seat, or the best injected plastic seat I have spare.
If I display my model somewhere that a viewer can peek in my cockpit and tell me that my instrument panel has the Altimeter where the Mach gauge should be,,,,,,I will just distract him by asking him to tell me some of his flying stories. And let's face it, most modelers don't know things like Phantom rear cockpits well enough to know that an RF-4B is the exception to the "no console" in back of Naval Phantoms rule. (so, I make sure I put that console in every RF-4B, lol)
I agree with Don,,,,,,the cost of modeling stays fairly constant whether you detail or not, I go for the "most for the least" approach.
I do have a deadline of sorts,,,,,,I don't want to be the guy that built an aircraft for only 73% of the carriers from CV-1 to CVN-76.
