RE: 21 Tunnel Talk
Ya might be better served goin with the TS3.
Reason is depending on the production run some VS1's had voids in the seams.
Where the transom joins the center section and sponson sheeting.
JD has a neat check if you have a suspect seam, Just run some thin CA along the seam.
If it wicks in ya got a void, If it rolls along ya dont.
Dont get me wrong Im a nut for that boat on my third right now, Just fair warning.
TS3 is purdy much plug and play just follow the instructions, Tower has sales on them all the time,
