I hope this isn't too close to double posting, considering it's been about a month and this post should be somewhat useful, being my impressions of RDF, and stuff.
Basically, RDF is a very nice part, however, it has a couple of weaknesses, like all pure-rubber tips (though it compensates for them better). Basically, it is just short of the stamina safety level for me, Hell Libra 100R2F can OS it sometimes (on MF-H Duo Aquario BD145RDF) and MF-F Phantom Cancer AD145RF (Attack mode) does so even more regularly. It also has all the opposite-spin weakness of RS/RSF, it seems. That said, I do prefer it to RS, it seems to have better stamina, as it has better balance due to the plastic ring, which also gives it a little extra Life-After-Death.
More importantly, I aim to try to do
this thing from the advanced forum tomorrow, to provide the required data. The rest of you should try to do so too, with whatever parts you have (a wheel like Death, or Libra if it doesn't get blown away
too bad (Arupaeo mentioned not using Basalt (and obviously not BD145 as it introduces too many variables)). Something like MF-H Libra GB145RS/RSF/CS/RDF or MF-H Death Aquario GB145RS/RSF/CS/RDF against whatever attacker you use (in right spin, and left, if you can).
