Why not std AP3519 or AP3519XS poles? The single spreaders are an extra $1000 and they are not any longer. Yes they will be stronger but I don't see anyone having problems with Lee Jrs and std poles.
The spreaders are bulky on a small boat.
I picked up a set of 19’s off a 25 Carolina Classic. Same circumstances, couldn’t pass up the price. Still playing around with fitment, and the standoffs for the standard 15’s does not work with the 19’s. I am going to reach out to Lee’s for advice, they are good to deal with
