I have the one pictured by chrisgarret and yes, I also use a longer bar.
Rubrburnr, alas, I haven't done much to it since the transmission puked on me around the middle of the year. I was going through some shakedown runs and the first time I really got into it it pulled very hard in 1st, shifted strong into 2nd and pulled great. Then when 3rd's turn came, it came apart. Limped home and was bummed. Just now got all the parts together. I'll send you some pics when I have some that don't look like a disaster.
Take it easy.
