I bowled on Montreal on fairly new synthetics and wished I had a strong Asymmetric with me when I did.  Montreal, while not the longest, is the highest volume WTBA pattern.  For me, it played pretty slick compared to the other WTBA mid-length patterns.

Unless they changed things from when I bowled on them, 3 patterns (Tokyo, Seoul, and Los Angeles) had more volume than Montreal.

I used a Wicked Siege and a polished Nuts Pearl from fairly deep inside with pretty good results.

depending on your game and lane topography. you should be able to start with the tour solid playing pretty straight up the track 5-7 board. if needed you can ball up to the nano or zero gravity depending on the shape youre looking for. and you have the endless at the top if you cant get anything to wiggle.  the tour  pearl and marvel pearl will be good on the transition. remember to take what the lane gives you instead of trying to force play an area of the lane

Montreal - 27.55ml
Tokyo - 26.2ml
Los Angeles - 26.1ml
Seoul - 25.1ml

How long ago did you bowl on the patterns?

I've been seeing two dif pattern graphs for this pattern. . one mostly reverse oil, one around half n half forward/reverse.  Which is the current one?

I bowled the Western Canadian Open 3 years ago in Edmonton on 1yr old prolane  and Montreal was damn slick.  I had a Lethal Revolver sanded down and played straight up 4 board to make the finals.
I recall everybody using surface and the guys that scored were never left of 12 at the arrows and pretty closed with their angles.  Bring your strong, early rolling stuff.

Ended up playing my iq tour nano and pearl.. laying it down at 20 rolling 15 @ arrowswith 8 as bp..
