All Shimano derailleurs I've used, back to pre-indexing slant parallelograms and up to recent LX models, will friction shift 8 cogs very well. (9, too.) It never even occurred to me to replace the jockey pulley.
Try it first and see. One of my last commuting derailleur setups was a "quasi halfstep" 47/44 with a 7 speed cassette. The middle 5 were half stepped, the outer -- at 13 or a 12 -- was for downhills, and the inner was a 34, a big jump from the penultimate 24. This was a bailout. It shifted fine from the 24. Shimano 600 (I think; square design, slant para, looked like first Deore but no housing tension adjustment) pre-index long cage rd, Record dt shifters on those briefly sold but very nice that put the levers just inboard of the brake hoods.

Much of what goes by the name of pleasure is simply an effort to destroy consciousness. If one started by asking, what is man? what are his needs? how can he best express himself? one would discover that merely having the power to avoid work and live one’s life from birth to death in electric light and to the tune of tinned music is not a reason for doing so.”* * -- George Orwell, Pleasure Spots* *Though I speak with the tongues of men and of angels, and have not money, I am become as a sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not money, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not money, it profiteth me nothing. Money suffereth long, and it is kind; money envieth not; money vaunteth not itself, is not puffed up, doth not behave unseemly, seeketh not her own, is not easily provoked, thinketh no evil; rejoiceth not in iniquity, but rejoiceth in the truth; beareth all things, hopeth all things, endureth all things. . . . And now abideth faith, hope, money, these three; but the greatest of these is money. * * -- George Orwell, Keep The Apidistra Flying* -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
