I have a 2635 with DL250 FEL bought new about two years ago. The 2635 is considerably more tractor than is the 2615 yet the DL250 FEL is the MF supplied FEL for it.
I've used my set up with a heavy (approx 750 lbs.) 66" Edge grapple bucket (designed for a skid steer) to move many trees and stumps last summer to clear way for a new 1000' driveway. During this process I frequently moved debris that was too heavy for the tractor/FEL to lift. There was no indication that the FEL was too light. Rather, the load simply unloaded the rear tires such that I needed to travel backward, effectively dragging the load in order to avoid the added time of cutting the load(s) into smaller pieces and making additional trips.
I would nave no reservations using a DL250 with a considerably smaller/lighter 2615.

Appreciate the info, the specs on the DL250 seem more in-line with what I am looking for, the newer 911 FEL specs don't match up exactly, but seem less in key areas.
The old MF 250 has wheel weights and ballast in the tires, but often seemed to struggle with lifting a 5' general purpose bucket full of horse manure/wood shavings/sawdust. And with a 2wd tractor, trying to backup in any mucky conditions with a full bucket was...frustrating.
