I have the ARC rims on Pro 4’s which I think are the same rims on the Heists and they seem pretty good so far; easy to set up tubeless and give the tyre a nice profile.
My experience of Easton hubs isn’t that bad. I ran a pair of Havoc’s on various bikes for three years without issue. I had to change the rear hub bearings once and the front had just died when I had my bikes knicked. The rims were champs too; despite lads of dings tubeless tyres always seated and held pressure.
Also had the DT M1700’s which were good wheels; stiff, reasonably light, easy to service and set up tubeless. I picked them up for a good price firm Rose but costs seem to have risen. I was going to get the same again when I replaced my stolen bikes but it was cheaper to get Pro 4’s built up on Easton ARC30’s.
