I'm in Fort Worth, TX and when I look at an online chart for the 'R'
value of insulation I would need for my attic, it tells me 49. (about
14" of cellulose. I think)

At the local DIY store they tell me that this is really overkill and
that about 30 will do about all I need.

Since we will be doing the 'blowing in' ourselves, I would appreciate
it if someone who has done this themselves, in this area, would care
to give their opinion of what 'R' value I will need.

Thanks.

Lewis.
