I would echo the comments about shorter handles being preferable, at least for me. I do like heavier handles, however. Both the Muhle R89 and the Edwin Jagger DE89 mentioned here are excellent choices, but I would toss the Merdur 34C heavy duty short handle razor into the ring. I prefer it to the DE/R89 series of razors, just as comfortable and forgiving, IMO, but a bit heavier and grippier in the hand. It is my favorite modern razor.
John, there is also a short handle Edwin Jagger called "Kelvin". It's roughly the same length of the 34C and comes with a good looking knurled pattern (pic below). It's available only on Amazon UK.
