Must depend on the guard and how it's fitted. I had them too (still using rear Mini V because cantis foul my rack mounting) but couldn't get them to work properly with 42mm SKS Bluemels. They either fit under the cable but with a pointlessly large gap between tyre and guard with mega toe overlap, or appropriate mudguard coverage with severe rubbing of the guard on the cable. Didn't want to flex the guard to make it fit at both ends because I've had too many plastic front mudguards fatigue and fail as result, hence switched to front canti.
@AussieHoss Mini V won't offer adequate space for mudguard between tyre & cable. Go for a Full sized V
