Mortising Router Bits

[grumpy6165]

I'm expermenting with making tenon and mortise joints on a Rutland Router Table. I seem to have cracked the motise part with a Yonico upcut sprial bit. For the tenon I have noted the
Whiteside 1304 Mortising bit seems to be popular. But would welcome any other ideas from the learned members of the forum.

the leigh fmt uses spiral upcuts for both bigger is better for tenons though.

I've just now ordered the Whiteside bit(also for use in the Rutland's table, with a Trend T11 fitted). Alternatives appear to be sadly lacking in the UK.
If it does what I want, I'll pick up a couple more.
