It can actually depend on what your needs, as well as expectations are. I've had great relief lines, 18 days off, etc. And I've had crappy relief lines, min days off, 4 on 2 off the ENTIRE month, working most weekends, right at 75 hrs credit for working 18 or 19 duty periods in the month, etc. With the kicker being NOTHING to trade for in the SLIW due to 30/7 issue, or the 4 on 2 off, or losing pay credit in the process of the what's left over. So those months, a 4 on 3 off Monday-Thursday long call line IS better as far as QOL goes. The rest is up to the individual persons knowledge of the contract and how to "game" the reserve system. Whether you want to work the Monday-Thrs, or simply sit home most of the month with just an occasional ARC sit thrown in.

And nope, you don't need to point out the pitfalls of long call, of which there can be many. Again, it's about managing expectations and exploiting the contract to the fullest extent, I've done it plenty in the 7+ years in EWR, IAH, LAX, and ORD.
