If your mod does not require them, keep it simple. Do the extra cost/labor for valve cover gaskets and tank removal. Tin men push them so that can cut time from an installation. Then chop off the original with bolt cutters. Hopefully, no shards of metal fall in. Hopeful, adjustable don't come loose. Been round and round on whether to us Loctite or not (that fine thread should not come loose if tighten correctly). Hopefully, they set them correctly in the mid range of the hydraulic plunger. ALL JUST MY OPINION.
Pretty cool how cvaria has weighted them Only thing important to me would be the rod itself. I would have never guessed the adjustable is only 3 grams heavier. That is only .10 of an ounce. So that is not big deal. That larger tube must be a thinner wall.

I've always used solid pushrods, if I need to tear down I do not care if I don't have adjustables. Smith bros will make high quality solid rods for cheap. I now run adjustables because I switched to hydosolid lifters. But, this is on an xl and they don't have collapsible covers from the factory. And I didn't want to spend the cash on adjustables, and a collapsible kit.
I use Smith bros pushrods in both of our 4k hp outlaw funnycars and if they'll hold up to that then they certainly should hold up to a tc that will never see 9k rpm lol.
i run the rivera adjustable p/r's and colony collapsible tubes
the reason is i also run lifter spacers. the setup is like running solid lifters.
advantage:
no worries about pump up or collapse
no worries on start up
i run the limit on the rpm scale
i run just enough spacing to quiet the valve train. 1/32=.03125 /6 (hex flat)=.0052 X 4 (flats)= .0208 x 1.65 arm ratio = .034 stem clearance. but the hydraulics picks this up.
also note: running solid on a hyd cam changes the way the cam functions and can HURT or HELP depending upon grind profile. on my set up it is a positive.
