GPX clutching

[bigdirt250]

I have a 75 gpx 433 with a 102c comet primary,I have both a gpx secondary and a 76 srx secondary but dont know which to use, and what spring pressure (hole&twist) to try.Would anyone share their clutching secrets for 500 feet drags

100% USE THE SRX SECONDARY. I WOULD START AT LOCATION # 3 @ 90 DEGREE. NOW A FYI FOR YA. THERE ARE TWO HELIX,s THAT WERE USED IN 76. A STRAIT ANGLE AND A MULTI. WHAT YOU HAVE THERE. 3:16 (yammie tony)

I have the 8A5 helix. At hole 3 and 90 degree twist. Using a fish scale and C clamp how many pounds of pull pressure should I be looking for?

 

[YAMMIEGOD3:16]

THATS A 76 340 SRX 42 DEGREE STRAIT ANGLE. WHAT ARE YOU SHOWING FOR PULL PRESSURE ? 3:16 (yammie tony)

YAMMIEGOD, do you have a weight and spring primary combination you would use, for a comet 102 C for 500 feet on my 75 gpx 433 stock with 36mm mikunis

B'' WEIGHTS WITH A PURPLE SPRING IS A GOOD START. 3:16 (yammie tony)
