Would you mind telling me a bit more about the drawbacks?
On what machine were you running, how was the memory usage of the module? what version were you running, were you able to fine-tune or cache the templates?
Would you suggest another systen then Petal, since it's not mentioned in the other nodes that go about this subject, and the fact that it's supporting international (i18n) makes it interesting for me, and i'm quite charmed by the way the tal-tags are implemented in the xhtml-tags. Till now i allways was using HTML::Template and HTML::Template::Expr.
The newer HTML::Template::Pro i wanted to trt did not compile on my machine however.
