No no, sprayer is the cheaper version of the scratches. (I'm pretty sure)
The sprayer was like $50 cheaper then the scratch FS was in 05/06. Maybe a bit more cheaper, I can't really remember. I think its lighter, but less durable.
WRS are lighter than the 05/06.
I have 165 05/06 TMs, way too short on me, but honestly far as I recall I have a feeling they weigh just as much as my 182 scratch wrs, maybe a bit less.
