Light hoppy ale recipe advise

[charliefarley]

Greatly borrowed from a few posts on here I have come up with the following for a summer ale:

Expected OG: 1.045 SG
Expected FG: 1.010 SG
Expected ABV: 4.6 %
Expected IBU (using Tinseth): 31.1 IBU
Expected Color (using Morey): 8.2 EBC

Pale Ale MO 4.000 kg 95.2%
Carapils Malt 0.200 kg 4.8%

Challenger 8.5 % 10 g 10.3 Loose Whole Hops 90 Min From End
Cascade 5.5 % 30 g 14.4 Loose Whole Hops 30 Min From End
Bobek 4.0 % 20 g 7.0 Loose Whole Hops 30 Min From End
Cascade 5.5 % 20 g 0.0 Loose Whole Hops At turn off
Bobek 4.0 % 20 g 0.0 Loose Whole Hops At turn off

Any thoughts?

For my own personal taste I would say ditch the Bobek and just up the amount of Cascade.

I've never used bobek, but have recently had a pale ale from a local brewpub that came in at 4 1/2% and 32 IBUs from cascades that was pretty good. They used centennial to bitter, but challenger and cascades should go good together.
Which yeast are you going to use?
