I'm not convinced about the value of the Srixons. If we simply divide the price by the number of dots you get a cost of 22.22 credits per dot for Srixon and 21.74 for Callaway.
That may be over simplifying it a tad but if WGT do ever offer custom designed balls you can bet the price will be per dot.
If you're not competing in money tournaments, maximizing your credits per dot has to be balanced against minimizing your outlay per round. Spending 25-30 credits per round on Callaways (250 cr/3 balls/3 18-hole rounds per ball) may not be viable for many players.
I used Srixons until I got good enough to compete in Tour Master RGs, when I switched to the L33 Callaways. I used those until I was competitive in Legend RGs, at which point I moved to L61 Nikes for the extra feel (very helpful with the R11 irons). Perhaps I'll switch to one of the L90 balls sometime.
I know many high-level players prefer the L33 Callaways, but I'm not good enough.
