this subject has been talked about allot. seems to me that it all depends on the person and what they like to feel when ascending and descending. i like bee line too. its kinda my meat and potatoes for hitches. the best hitch i have used was 3/8's OP and 5/16s all gears tech cord. super smooth on half inch ropes. 5/16 beeline bits too hard on half inch arborist ropes. the 3/8's is allot smoother. with 7/16 lines i often find that the 5/16 is just right and the 3/8s is a bit too slick for me. i use a 4 wrap distel and i weigh 160, 180 when fully geared up including climb saw.
once you find the cordage you like, dont buy them with pre made eye splices, buy the long lengths and possibly learn to splice them yourself this will save you alot of money.
also i just started learning to splice. it gives you more confidence in the cordage since you made it and know how strong it is.
