First of all I'm new to this forum, but I wanted to thank you all for all the advice I've been reading. I've got a Problem I think

I'm in Canada and decided to regrip my Callaway X-18's this year. Well I approched golftown up here and they quoted me $13 a club for Grip (Golf Pride DDR) and install. Well times that by ten and I thought that it was a little pricey to do. So I searched out doing it myself, hence this forum. I found Golfsmith has a canadian website and proceeded to order 10 Grips, Solvent, 1" Tape, and a Vice holder. Started my task last night, cut off the old grip, put the tape on, applied the solvent and installed the new grip.... Did this on 2 clubs before I realized that I forgot to take the backer off of the 2 sided tape. For some reason I was thinking that it was Solvent activated tape (my bad, was a long day at the office yesturday) Anyways here's my breakdown of my clubs last night.
5 iron (left on tape backer when installing grip)
6 iron (see above)
7 iron (removed backer, but tape was a little lumpy, doesnt seem to affect my grip)
8 iron (see above)
9 iron (ran the tape in long strips from top to bottom, made for a very easy install)
PW (see above)
GW (see above)
SW (see above)
Anyways I tried to pull off the grip from 5 and 6 iron, they wont budge (so I'm wondering will they be ok for the season till I regrip next year) or does someone have advice on how to pull it off so I can reuse the grip?
next question, just to make sure I did it right,
Step 1 cut off old grip
Step 2 used heat gun, removed old tape
step 3 applied new tape (properly :

)
step 4 used Solvent I bought from golfsmith (in grip and then applied from all over new tape)
Step 5 Rubbed solvent lightly over tape to make sure it was properly lubed
Step 6 Slide on new grip, then straightened it out.
Step 7 Let it sit over night.
I guess if you could supply some advice and comments I would appericate it.
Thanks Mr Winky
