USE: Wife and I cruise lake and occasionally pull our 17 year old on tube. Want to be able to give him a good ride but we only have a few more short summers with him, then it's just the 2 of cruising around. We will be on an open part of the lake that may have a few more waves than the channels.
LAYOUT: Wife wants Dual Helm Captain chairs so she sits beside me, not behind or in front of me while driving.
NEW/USED: We would like something for this summer (few left with our son). Finding a good used boat with the layout we prefer is challenging and I know this isn't the best time of the year to buy so we are ok with buying new to get what we want.
SIZE: We've been told conflicting info here. Some say 20' or above will be fine. Other say go 22' or above. What say you?
PONTOON or TRITOON: We've been told conflicting info here as well. Some say for the 20-30 times over the next few short years that we will be pulling our son on a tube that a PONTOON will suffice. Others say PONTOON is not going to turn well enough to give him a good ride. (He is 17 years old, so dad can't give a lame ride...

BRAND / MODEL:
We are trying to stay local. We've eliminated some dealers just because we couldn't get any help. So we've narrowed down to 2 boat models we like and I'd like your opinion.
STARCRAFT - Pontoon: EX 22R w YAMAHA 115hp = $30k or Tritoon: SLS-3 w YAMAHA 150hp = $39k
BENNINGTON - Pontoon: 22SSRX w YAMAHA 115hp = $36k or Tritoon: 22SSRX w YAMAHA 150hp = $45k
The STARCRAFT SLS-3 checks off a lot of boxes on features and the color really appeals to us.
HOWEVER, we read that BENNINGTON is a premier manufacturer.
This is a lot of money either way so we want to make a good decision.
Thanks in advance for your advice.
