As long as they have more than 3 available wheelchair spaces above ground level then I guess they can keep the front-loading but I won't be sitting on the front row. I hate to imagine how many hours of rugby I've missed behind people's heads who are late to their seats or wobbling off to get the next round in (and then again when they bring it back). Personally prefer back-loading because the front row tends to be the easy option in terms of "where to bung the wheelchairs". If there is accessible seating further up then although it won't (hopefully) be me, there will still be other people missing 5% of the season...
Bothof those things should be accommodated - the needs of those in wheelchairs should be addressed properly and sufficient higher level easy access places should be made available , as well as pitchside if required.
I also think it is important for frontal access to the stands , not necessarily for that fact alone , but having the concourse and connection to the pitch / players is an important part of the 'rugby club' feel .
I was at one of the supporter forums where that very point was made and Levi Harris and his team accepted that both of those items were important .
