firstly i dont want quins or london rl not to have a team in super league long term,however its pretty clear that they can not be sustained in their current format of losing money hand over fist.
now for me the senseble option would be to take a gap year or two in the championship and rebuild the from scratch "again".if they are confident that they are producing good quality kids then they should be able to field a near full southern english side,they then need to find a venue that is accessable to the london public without been too far out,ive travelled from inner london on a few occasions to the stoop and its a logistical nightmare especially when trains and undergrounnd are shut for works over a weekend and then with this hassle you understand why they get little support.
