Pils malt : rice ratio

[gmac]

I am going to do a beer for the neighbours.  I've put this off long enough but I guess I need to do a BMC style just to get it done.
So, my question is simply this.  Is there a ratio of how much rice a lb of pils malt would convert?

My first (and hopefully last) recipe attempt is just.
7 lbs pils malt
2 lb minute rice
1 oz Hallertau (5.6% AA) at 60 mins
WLP Mexican Lager yeast.

Any problem with this converting over a 1 hour mash at 150?  I don't really want to get 6 row just for this.
Thanks

You didn't say who's Pils malt, but that would work.

The weighted average would be (7*110+2*0)/9=85.6 ^oLintner, which is more than enough to convert. Munich II (in the 10 L color range) can be in the 30-40 range and can convert itself.

Weyerman Pils.  I tracked down the Weyerman distributor here in Ontario a while ago so I could buy direct from them and avoid the 40% LHBS upcharge.  But, they only handle Weyerman, OIO 2-row and Muntons so that's what I use.

Midwest says that is 76 Lintner.

That puts you at 59 Lintner for the weighed average. You are good to go. Not real high, but it will work.
