Service reliability in Maple Ridge enquiry

I'm currently on 25/3 DSL through Lightspeed, and was contemplating moving to their 50/3 cable offering. I am however, wary of peak period congestion where 50Mb slows to more like 5Mb. Can anyone chime in as to performance in the Maple Ridge area, specifically in the: 224 to 232 and 132 to 136 area? (I don't know how far a typical node spans, it could be far larger and area than what I've outlined) I know this is a Shaw forum, but Lightspeed will be getting their access through Shaw in the area, hence my posting here. Thanks in advance for any replies.
