Changed my driver shaft and now I'm slicing for Ireland

[jfrain2004]

I had a prolaunch red Stiff in my Cobra 9.5 Deg driver up to last.  Had a fairways hit % around 60 - 70 % and averaging around 240 yrds so was very content with that.  Then on the 1st tee last weekend I took my driver out and when I looked down at the head the face was looking up at me. Seems something fell on my golf bag and the driver head took the brunt of it.  So off I go to get a new shaft and for the hell of it I said I would try the prolaunch blue stiff. Hits the ball higher for more carry I think I read but wanted to try something different anyways.  So put the shaft on and out of the first 10 balls I hit at the range 9 of them went out right,  out over the fence.  Slice slice slice.  I thought I was going to get some more carry but now have a driver that I daren't use on a course till I sort the shaft.  Is it just a case of going back to the tried and tested ProLaunch red or is here any other reason for a shaft to cause a slice,  and it must be the shaft cause I the same driver head,  setup,  grip as before was not doing this :(

If you rely on any alignment marks on your grip, did you check to make sure the head is installed in line with the grip?

If the shaft is defective (cracked) but not visible to the naked eye...?

Did you let others hit the club, especially the person who put the club together?

You went from a piece of rebar to a wet soup noodle. Those shafts are 2 totally different animals.
