My family is new to wakesurfing, but have started trying to learn over the last couple weeks. We started with a Swell wakeshaper and (per the instructions) both rear bags (stock) and the center hard tank 100% filled, and the wake plate all the way up. Bow was riding very high and wave was decent, but seemed short. Things improved when we added people weight to bow of boat. Wave got longer and riders noticed the improvement.

This is leading me to want an IBS system. Went to Wakemakers site and there are three options for a piggyback IBS system:

Flyhigh 425lb bag: $399
SL Sumo 500lb bag: $295
SL Sumo Max 750lb: $334

On that page, it recommends the 500lb bag for my 2013 LSV. I called customer service and was told to go with the 425lb bag (they said it fit better). I look on the forums here and see strong recommendations for the 750lb bag.

Can anyone with a 2013 (or similar) LSV help me with what works best? Don't really want to spend more money for a smaller bag, but also don't want the seats popping up or to have to take out the cupholders.

Any advice would be greatly appreciated!!!
