I got a couple of tucks of Voskhods from @dangerousdon when I first joined B&B. His only request was that I post a review of them eventually. So...
I alternated between the EJ DE89 & the Maggard V3 head & MR5 handle for each blade. Used TOBS Sandalwood soap mixed w/ 15 drops of glycerin for all the shaves/blades as well. Results were fairly consistent blade-to-blade (though the V3 seemed more aggressive than the DE 89.) Got 8 shaves out of each blade. The last couple of blades "seemed" to have a bit less irritation on shaves 7 & 8, but... it still felt like I was pushing it & could have stopped @ around 4-5 shaves. I did get some nice razor burn on one of the first few blades during one shave, but I attributed that to first use of the V3 head (I personally thought was a lot more aggressive than the DE89.) I think the better results on the later shaves on the last blade was because I was being extra careful about pressure/angle ==> took my sweet ol' time. But I also feel that the trade for less irritation was not quite as close a shave.
Anyway... that's the opinion of a relatively new DE shaver. So... take it for what it's worth...
