I've used nothing but the Shock Doctor Pro's in the past (nothing bad to say about those, especially at $7.50 a piece). But, after hearing about the SISU from some guys I play with I figured I give it a shot. Seemed silly to pay $25 but after using one while playing, it's a world of difference.Pros:
With the mouthpiece starting flat and pliable, molding to my mouth was a bit of a task. Took me 4 times to get it right. Amazed the way the mouth piece went right back to its original flat shape upon reheating.
- Ability to reheat and fit without ruining the mouthpiece.Cons:
- Slim design (really is easier to breathe, talk and drink)
- Not real sure but interested in seeing the longevity after multiple uses and remolds
