Returning to pre-patch version...best way?

[jamesdietz]

( Posted under bus issues for newest patch as well, but I thought I might have better luck here,with last few questions on what to do next.)
After a couple of days of fiddling & using,I may go back to what I had before patch ...maybe even do an entirely fresh install.Here are my niggling problems some of which undoubtedly others have had as well:
1.) My onscreen plane customizer no longer works.When I change cammo or markings generally nothing happens,however in flight I do have the "new" plane.
2.) Initially inflight ib cockpit,exterior parts of my plane appear white.Hitting exterior view I have cammo'd plane.Hitting interior view again ,I now look out on cammo'd/marked aircraft.
3.) Lots of wierd things happening in various cockpits , already noted in detail by others in this thread.
4.) No real increase in FPS...at least not enough to deal with the problems this patch seems to have caused.
I do have a serious question : I saved both Stem & 1cSoftclub folders before patch.Would it be better at this stage to simply use these to overlay what I have or do a fresh reinstall...or for that matter simply delete the new patched "Parts" folder & slap in the old one in its place?Wait for the Official "Steam" Patch & continue to grumble under my breath...?
(Or should I place this post in technical issues?)
