I prefer the SV98. First is because the durability is much better than the SRV5. The second reason I prefer the SV98 is because it is just as hot as the SRV5 but I feel it hits the 52/300 better. Finally, the third reason I prefer the SV98 is because even though it is still a 12" barrel, I feel the sweet spot is much bigger in the SV98 over the SRV5.
I know I need to update my review thread on the SV98.......It has taken me all summer to get around to swinging the SV98 over the Stealth and Synergys haha. I'm really glad I have because lately the SV98 has not seen the bat rack at all since I discovered it's hottness. Also, this fall season I am playing with the 52/300's twice a week whereas all summer it was 40/375's. The SV98 that I have all spiraled up (still good enough to get by an ump who isn't looking for it), is out hitting my webbed up ratteling SCX3 with all 3 balls I have been BPing. 40/375, 47/500, and 52/300 balls.
You really can't go wrong either way honestly, but if the 52/300 is in your future, you want the SV98 IMO.
