Default Biscuits vs Tongue and Groove Joints

I am rebuilding some garden furniture with new cedar wood. The joints on the back frames are unglued tongue and groove. I assume they are just to keep the back frame from twisting and that's why they aren't glued. Could I use biscuits for these joints instead of tongue and groove?
I am having a lot of leg problems lately and I am looking for the lazy way to do things I guess. I could do the tongue and groove but I have to set up two separate routers to do it. Biscuits would be much quicker. I just want to make sure the joint will be strong enough.
Any thoughts are appreciated.

Deb,
IMHO I think biscuits would be adequate for this application. I would however, suggest you use an exterior glue, maybe even one of the polyurethane glues. Though the cleanup can be a pain, they will fill any minor voids in the joint and help prevent future water intrusion.

Thanks Tim! Would Titebond III be adequate? It's supposed to be waterproof once it's 100% dry. I can keep the benches indoors for 24-48 hours to give the glue time to dry.

I think biscuits would work OK and the tightbond 3 is great, Instead of biscuits you could always use a spline in your miters quick and easy on the table-saw.. 2nd thought biscuits are faster...
Whats the cats name?

There are actually 2 cats in the picture. The black one is Little Guy and the tortiose shell was named Little Bit. I called her that when I found her when she was about 3 months old, and weighed less then a pound. Now she answers to Fatty.

Thanks guys! I've got three frames glued up so far using the biscuits. Worked very well!

You're better off than many, Deb. My neighbor's cat only answers to the sound of the electric can opener running!

Oh she loves food! Her favourite is chocolate pudding. I think that's how she got to be "Fatty". She is a very strange cat but totally loveable. She follows me around like a dog. Loves to be out in the shop with me. Gets into and onto everything. If I start something up she leaves but waits on the other side of the door for me no matter how long I'm in there. Hard to beat a friend like that!

Deb, Tim is my kind of man. I love biscuits because they're done in an instant and modern adhesives are stronger than the wood.
