Nothing better about the solid tube unless you plan on moving it or taking the bolt in and out. The hollow ones will be good for about 3-4 tightenings before it starts mashing the tube creating slop. That is unless you feel the need to overtighten it you can mash it the first go round.
Believe it or not most ran on els had the rf slid all the way out.
Most that went indoors slid all the way in on dirt.
Most outdoors avg tracks dont move it from stock.
Small tight tracks like it slid in in most cases.
