I would rather suggest using `<C-v>{` then `(<Del>`: no need to move
hand to the other block. And, of course, if using my mappings instead
(`,s` for `()`, `,h` for `[]`, `,u` for `<>`, `,f` for `{}`) `<C-v>`
will not be needed. One of the reasons I keep using them is that
typing them is faster as they do not involve higher row (and shift
should you use `us` keymap) and positioning for both keys may be
performed simultaneously as `,` is to be pressed by one finger and
everything else by others.

Also all your mappings are incorrect: first ones use `<BS>`, pretty
much sure you meant `<Left>`. As for the last one: it ignores
&shiftwidth, using two space indent always. Just use

inoremap {<CR> {<C-o>o}<C-o>O

Most of time indentation will be just fine due to indent scripts,
including additional indentation on the new line created by the last
`<C-o>O`.
