cf7go - if you like journeys, then go ahead.
Personally, spend the money with a good instructor that communicates well with you (you might have to try several).
Just for B.S. went to skeet range yesterday to verify my previous follies of purchasing chokes, ammo, etc. @ station #4:
Here was the verification - from a 12ga. .740 bore (mic'd), using flush Winchester factory chokes (inv.+), Winchester factory upgraded chokes (Winchester Signature) Extended, and Wilson Precision Extended Ported using the following ammo (AA 9's @ 1 1/8 oz., @ 1200fps., Kemen 8's @ 1 oz., @ 1210fps., Remington Shur Shot 8's @ 1 1/8 oz., @ 1250 fps.) - could not tell any difference in performance or the breaks using cylinder, skeet and imp. cylinder a little bit better breaks (but missed a few more).
