No opinion, but a modest, relatively inexpensive idea, that I have been considering for myself. How about one of those Finale CF bows for $340 to:
- have a stick that you can take out on gigs with your Cleveland and not worry about bringing home kindling at the end of the night
- get a feel for a somewhat heavier bow

As I mentioned above, I am using a light bow (just checked the weight; 127g, too, after recently having some work done). For me, my intermittent arco-suckedness has more to do with hand/arm/body tension, "thinking" instead of "playing", etc., more than the bow weight. Then, in my case, there is simply inadequate practice time, these days.
I have been without a teacher for awhile. I notice that my hand position has crept into something not so good. As I practice in front of a mirror and put my hand back in the right shape, suddenly my bow works much better. Hmm.
I can sound like garbage with any weight bow. I am guessing that both of us have right arms that are plenty heavy enough to get the strings going; for me, anyway, its more a function of how I am moving.
The bowmaker I go to told me that the current trend is toward about 140g for orchestral playing. That said, a nice, light stick, like yours or mine, may, perhaps, be less of the problem than arm tension, wrist movement, fear, conceptual failings, grip, etc. At least, that's definitely the case in my own little life.
Another (cheap) thought is to try some Kolstein Soft in conjunction with the Oak Soft.
I am doing this blending thing, currently, 1-2 swipes of Kolstein, followed by 1-2 swipes of Oak. The Kolstein definitely lets me move more air with the bass, with more grab, and the Oak is smoother and sweeter sounding. Helps me relax my arm a bit more. For me currently, its white hair with BelCantos.
Black or S and P hair is an interesting variable. Different things for different setups, basses, and times. One of my fomer teachers used to only use white hair on his Siegfried Finkel bow, now I see him using salt and pepper (with Spiro Weichs and Pops).
Of course, I am now a dabbling amateur, so take all this free information and spate of rambling thoughts, at cost...
