Which cylinder for length work?

I am about to make the plunge for a cylinder, but am a little confused by different websites. I really don’t want to work more on girth now, being 6 mid shaft and 7 at base already. So is there a particular type of tube that works better for length, or are they all the same?

Thanks

Supposedly (can’t corroborate it myself yet) the non-flared thickwall cylinders some places like vacutech.com have are geared toward length gains.

I think the best thing to do is get a cylinder that is very close to your current girth which will give you more pull in the length direction and very little in the girth. Also I have hear cock and ball pumps are good for pulling the ligs and getting extra length but I can’t verify this yet.

Wrapping before entering the tube is another option to investigate, if you haven’t already…
