Not all knees were created equally! Mine gives me grief every now and then and I'm 32. Sounds like Eveready has magical genetics haha.
LoL I will use the clutch and save my synchros.. It's not a big truck with a heavy flywheel or whatever those things have to slow down input shaft speed change & make revmatching easier. I do double clutch and rev match the best I can but unless going into second at slow speed, I push the clutch in before changing gears.. I have a buddy who slips his clutch more than I do. Had a 2001 C1500 with a 4.3 and 5 speed he bought brand new. Had 240k miles on the original clutch before he replaced it and he only replaced it because he had to have the slave cylinder replaced and was there..
