I too mix my own. 50/50 pure tung oil/Epifanes spar varnish. I apply it only after first filling the pores with either straight spar varnish or epoxy, sanded back to bare wood and repeating until all pores are filled. Then I start oiling by wipe/rub on-wipe/rub off, leaving the surface "dry". The next day I'll scuff it with 600-800x, and repeat. Several coats is all it takes, determined by when it stops soaking into the wood, followed by a waxing with a quality paste wax.
I quit messing with Linspeed after watching the wood surface turn to mush when caught out in a rain storm. May not have been the fault of the Linspeed, per se, and it kind of soured me on oil finishes in general. Now I restrict their use to only those "safe queens" that may never see inclement weather. For the rest I use straight spar varnish, 8-10 coats rubbed out with 320x between coats, final coat rubbed out with rottenstone to cut the gloss, and then waxed to bring up a soft luster.
